PUMP' REGUL'ATING DEVICE SPECIFIOATION forming part of Letters Patent No. 291,271, dated January 1, 1884.

" Application filed March 26,1883. (No model.)

To ctZZ whom it may concern: I

Be it known that I, JAMES H. BAKER, of the city and State of New York, have invented an Improvement in Pump-Regulating.

boiler, and in some instances,where the water" of condensation is discharged at a lower level than the boiler, a pump has been employed that operates when there is a sufficient accumulation of water, and that stops, or nearly so,wl1en the water of condensation is pumped into the boiler.

My invention relates to the combination, with a steam-pump, of a vessel for the reception of the water of condensation, a steam pipe and valve operated by a float, and valves to admit the exhaust-steam from the engine to go to the atmosphere or into a coil, for Warming up the water before it goes to the boiler and condensing the steam of the engine, to avoid unnecessary loss of water.

In the drawings, Figure 1 is an elevation of the apparatus, partially in section; and Fig. 2 is a sectional plan of the water-vessel at the line as w.

The steam-engine cylinder A and its pump B are of any desired character. Usually they will be twin pumps, the one working the valves of the other engine, as in the WVorthington pumps. The engine and pump are supported at one side of the water-vessel D by brackets or otherwise, and the water of condensation from the steam coils or radiators is allowed to run into the vessel D by the pipe 0, and from the vessel D there is a pipe, E, to the pump B. Steam is supplied to the engine by the pipe 1 leading to the boiler or steam-generator, and in the pipe F there is a valve at G. A hollow arm, K, extends out from the side of the vessel D, and there is a lever, L, having at one end a ball-float, M, and at the other end a cross-shaft, N, with. a crank, 2, at one of its outer ends, with a link, 0, to the lever-arm 3 of the valve G. The shaft N passes through stuffing-boxes, so as to prevent leakage. As the water accumulates in the vessel D the float will rise, and eventually it will be lifted sufficiently to open the valve G through the medium of the cranks 2 and 3 P to the boiler.

float will fall, and the supply of steam will be I and link 0. The steam will now start the engine and pump, and water will be drawn from the vessel D and returned by the pipe As the water descends the lessened, and the speed of the pump will be regulated according to the quantity of water running into and to be taken off from the vessel D. The exhaust-steam from the engine passes by the pipe Z, and may be allowed to escape at the valve on into the atmosphere, or else when said valve m is closed the steam Will pass through the worm or coil within the water'in the vessel D, and be condensed, and the water of condensation will flow over from the upper end of the pipe It.

When the radiators are not in use and there is no water of condensation running into the vessel D, fresh water may be supplied into such vessel D by the pipe 10 from. any suitable head, and the steam-pump may be used for pumping water to an elevation or into a boiler.

The air-valve at 1; allows the escape of any air or gas confined in the vessel D whenever necessary.

At R, I have represented a gage to denote the pressure in the vessel D, and at S is a glass gage to indicate the height of water in said vessel.

I do not claim a pump-conncction with the vessel that receives the water of condensation. Neither do I claim a float to operate upon the steam-valve either directly or through the intervention of a roclcshaft.

I claim as my invention is- 1. The combination, with the closed vertical vessel D and the pipe for supplying the water of condensation to the same, of a hori zontal steam-pump, the frame of which is bolted to the side of the water-vessel, a pipe from the water-vessel to the pump, and a pipe from the pump to the boiler, a steam-pipe from the boilerv to the engine, and a cock in the same, a float within the closed water-ves sel D, a lever and a rock-shaft passing through a stuffing-box upon the water-vessel, and a lever and link from the rock-shaft to the steam-valve, substantially as set forth,whereby the water of condensation within the closed water-vessel is made to operate the steam-valve, substantially as set forth.

2. The combination, with the steam-pump Signed by me this 22d day of March, A. '1'). 10 and the closed water-vessel D of the steam- 1883.

valve G, a float and lever within the vessel,

and a connection to the valve to open and JAMES ll. BAKER. close the same, the coil iwithin the water space of the vessel D, and the exhaust-pipe and cocks, to cause the steam from the engine to pass into said coil or to escape to the at- \Vitnesses:
